Guidewires may be utilized to direct medical devices into a desired target vessel for intervention. Conventional guidewire methods and devices may include a steerable guidewire that is not anchored in any way. When tortuous anatomies are involved, the stiff device may work to straighten the guide wire as the device is advanced over the curved portion of the guide wire and the steerable guidewire may often slip back out of the target vessel making it difficult to use the steerable guidewire as a coaxial rail to guide a device into the appropriate vessel.
